Hi All,

Looking for advice on my next tire purchase and was wondering what matters the most for fuel economy.

There is no one tire I looked at that gives me the max in all catagories and is still at a decent price.

So I was wondering what the importance of the various ratings/sizes would be.

I'm going 17 in, 215/65/16 is stock and I want to go 215/60/17 or 225/55/17, most tires have 44psi max but some 51. Am I better off at a LRR large diameter 44psi or a non LRR 51psi with a higher load rating and slightly smaller diameter?
